Choose the odd one w.r.t eukaryotic cells.

Options

A. Cell membrane
B. Mesosomes
C. Lysosomoes
D. Ribosomes

Answer

To solve the question "Choose the odd one with respect to eukaryotic cells," we will analyze the given options: cell membrane, mesosome, lysosomes, and ribosomes.

### Step-by-Step Solution:

1. **Identify the Components:**
- **Cell Membrane:** This is a structure that surrounds all cells, both prokaryotic and eukaryotic. It acts as a barrier and regulates the movement of substances in and out of the cell.
- **Mesosome:** This is a membranous structure found in prokaryotic cells, formed by the extension of the plasma membrane. It is not present in eukaryotic cells.
- **Lysosomes:** These are membrane-bound organelles found in eukaryotic cells that contain hydrolytic enzymes for digestion.
- **Ribosomes:** These are the sites of protein synthesis and are found in both prokaryotic and eukaryotic cells.

2. **Analyze the Options:**
- The cell membrane is common to both prokaryotic and eukaryotic cells.
- Mesosomes are specific to prokaryotic cells and are not found in eukaryotic cells.
- Lysosomes are specific to eukaryotic cells.
- Ribosomes are present in both types of cells.

3. **Determine the Odd One Out:**
- Since mesosomes are not found in eukaryotic cells and are specific to prokaryotic cells, they are the odd one out in this context.

### Conclusion:
The odd one with respect to eukaryotic cells is **mesosome**.
